Problems uploading flash memory -- part 2

I have the same problem with the StratixIV GX Development Board and QuartusII 9.1. While trying to do the board recovery process, I discovered that there is an errata in the file "altera\91\kits\stratixIVGX_4sgx230_fpga\factory_recovery\build_factory_source\build_factory_readme.txt". It says:

Problem Description:

The release of Nios II EDS 9.1 tool "sof2flash" does not include support for Stratix IV GX .

Work-around:

.....

The described the procedure, but the 9.1.0 kit that I have does not have the required file "s4gx230_pfl_programming.sof" required to do parallel programming.

I submitted an SR and the response confirmed that this is a bug in 9.1. I have updated my SR to request the "s4gx230_pfl_programming.sof" file.

With respect to the .flash file size, the .flash file is in the SREC format which has a text based representation of the binary image. My experience is that this will be over twice as large as the actual binary image.
